Bison ZipCrank Basketball Goal Height Adjuster, BA980

The Bison ZipCrank basketball goal height adjuster is a durable, high-quality upgrade that turns fixed-height backboards into adjustable systems for easy transition between adult and youth play. This retrofit system provides infinite height adjustment from 8' to 10' and features easy-to-read height indicator labels. Height adjusts manually with the included hand crank, or faster with a cordless drill using the optional Drive Shaft or Winch Winder Kit (sold separately, see below). The welded, pre-assembled mounting structure is constructed from silver powder-coated steel for strength and durability. The system rides smoothly on two parallel 1" diameter chrome-plated steel rods that pass through self-lubricating bronze bushings for stable, consistent operation. The BA980 ZipCrank height adjuster is available in three models based on backboard size: the BA980F fits fan backboards with a 35" x 20" mounting pattern, the BA980RS fits 42" x 72" backboards, and the BA980RT fits 48" x 72" backboards. Please note that when installed, the backboard face will sit 4-1/4" closer to the free throw line. Dunking or hanging on the rim when lowered below 10' may result in injury and void the 5-year limited warranty.
